Yeah, it's as old as the Internet
Putting that aside, you said it yourself. That's not how you use a knife, so who cares if other knives did better? What is the point of testing something in a way it won't be used? Should one test cars to see which drives underwater longest before the engine cuts out? How about testing how it cuts? Now that's a test with conclusions that serve a purpose.
Yes, there would be a purpose in testing vehicles underwater, if you were going to be using one hard off road, and fording deep water crossings.
4x4's with snorkels, Military vehicles, amphibious vehicles etc get tested.
Would that test be reasonable for a Ferrari? Nope. For a H1, or Jeep Rubicon, or military transport vehicle? Maybe!
There, I got it out of my system. Noss's videos tend to be polarizing. Many times it is people angry over how "their" particular brand does.
Or, people angry that he is destroying knives doing really stupid stuff to them (the kind of stuff no normal knife user would do).
But, if a knife is marketed as "hard use" or "bomb proof" etc etc, it is interesting to see which ones actually are.
There are several "military" "hard use" knives that don't fare so well (some don't make it past the wood stage).
I simply file it away under "neat to see what a knife will take."
The "uses" he tests would not make sense with thin, high hardness knives optimized for slicing.
